In industrial applications, microcrystalline wax is primarily valued for its high melting point, strong viscosity, good ductility, and ability to prevent oil separation. Common uses include:
Paraffin wax modifier: Adding a small amount of microcrystalline wax to paraffin wax alters its crystal structure and improves its plasticity, making the paraffin wax more resistant to bending and moisture. This makes it suitable for use in waterproofing materials, packaging paper coatings, and casting wax.
Grease thickener: Due to its high gel strength, microcrystalline wax is commonly used as a thickener in instrument greases, sealants, and petroleum jelly.
Rubber and Plastic Processing: A blend of paraffin wax and microcrystalline wax can serve as an anti-cracking agent for rubber, preventing surface chalking and cracking, and aiding in demolding; it can also be added to plastics, textiles, and leather.
